Exploring New Worlds: The Rosetta/Philae Mission and its Challenges to Computer Architecture


Philae a comet Lander which is part of the ESA Rosetta mission successfully landed on comet 67P/Churyumov-Gerasimenko on November 12th, 2014. The landing followed a careful landing site selection process based on data obtained with the Rosetta orbiter instruments.
After several (unplanned) bounces Philae performed a First Scientific Sequence (FSS), based on the energy stored in it’s on board batteries. The touch-down dynamics, bouncing trajectory and attitude could be reconstructed a-posteriori.
All ten instruments of the Philae payload have been operated at least once. Due to the fact that the final landing site was poorly illuminated, Philae went into hibernation on November 15th, but signals from the Lander were received again in June and July 2015. However, attempts to re-establish reliable and stable communications links, unfortunately, failed. September 2nd, 2015, Philae could be clearly identified on the comet surface with the Rosetta Orbiter (OSIRIS) Camera. Shortly after, September 30th, the Rosetta mission was ended, by a planned impact of the main spacecraft on the nucleus.
The development of the Rosetta Lander goes back to the mid 1990ies, consequently electronics in general and its Command and Data Management System (CDMS) in particular, are based on (conservative) technology, available 20 years before the actual scientific operations! In order to combine radiation tolerance, high reliability (flight heritage) and low power consumption, two redundant RTX2010 16-bit processors, manufactured by Harris Semiconductor, have been used. Telemetry could be stored in a redundant mass memory with two times 16 Mbit capacity.
Rosetta is an ESA mission with contributions from its member states and NASA. Rosetta's Philae Lander is provided by a consortium led by DLR, MPS, CNES and ASI with additional contributions from Hungary, UK, Finland, Ireland and Austria.

ARM HPC : Supercomputing on a Lower Power Budget


ARM is the world's leading architecture, used in everything from almost every modern mobile phone to tiny processors embedded in the rapidly growing world of IoT devices. We work with over 1200 partners to deliver an entire hardware and software ecosystem to help seamlessly deploy our technology wherever computing happens. In 2012 ARM launched its 64-bit instruction set and, since then, the worlds of enterprise server, data centres and high performance computing have all opened up. ARM-powered servers are already available from silicon partners including Cavium, AMD, Applied Micro and nVidia.
In this presentation we will explore the growing ARM HPC ecosystem, highlighting the movement from early adopters into real HPC deployments. Work including the availability of the open source OpenHPC stack will be explained, along with the development of the commercial tools that are needed for real HPC systems.
The headline forthcoming system is Japan’s Post-K supercomputer, intended to be an exascale system available in around 2021. This machine will be built on the new ARM Scalable Vector Extension (SVE), which allows chip designers to build systems with vector lengths of up to 2048 bits. The presentation will also include an explanation of how SVE allows vector instructions to be written without knowing the vector length in advance of execution.

Short Bio: Based at ARM's Manchester Design Centre, Chris leads the ARM Performance Libraries development team. They are responsible for optimizing the ARM vendor maths library, which provides BLAS, LAPACK and FFT functionality. He is also heavily involved in developing the ARM HPC software ecosystem. He holds a PhD from the University of Leeds on efficient adaptive methods for the numerical solution of PDEs and he subsequently worked at the university for twelve years on research on a variety of HPC and numerical modelling projects. Before joining ARM he was part of the HPC team at NAG working on supporting national HPC services such as HECToR, the UK's supercomputer, and the EU exascale project EXA2CT.

Parallel Heterogeneous Node Programming: A Work in Progress


Individual laptops, desktops and the compute nodes of HPC systems have undergone a remarkable transformation over the past 15 years. Starting as (in retrospect) simple uniprocessor architectures with a few levels of cache, today they are powerful parallel heterogeneous systems with an increasingly complex memory subsystem. As computer hardware designers learn how to provide even more performance with acceptable power consumption, this evolution continues.
Early mainstream programming models and application programming interfaces to exploit intra-node parallelism made direct use of the multicore system’s major characteristic: the ability to support multiple independent execution streams, or threads, that share memory. Yet today’s platforms are much more complex, with a large core count, non-uniform access and potentially disjoint memories.
In this talk, I will discuss the development of approaches to parallel programming on the node, challenges posed by significant changes in both applications and architectures, and potential future paths.

Short Bio: Dr. Chapman is a Professor of Applied Mathematics & Statistics and of Computer Science at Stony Brook University. She also directs Mathematics and Computer Science at Brookhaven National Laboratory. She has performed research into parallel programming models and their implementation for over 15 years, with a focus on OpenMP, OpenACC and OpenSHMEM.

Collective Dynamics and Self-Optimisation in Large-Scale Networked Computer Systems


(Workshop: SAOS)
Today’s networked computer systems have reached a complexity and scale that pushes existing modes of operation to their limits and beyond. Developing adequate self-adaptation and self-optimisation mechanisms therefore is vital for the reliable and robust provision of services and maintenance of the underlying system infrastructures. Cross-layer and system-of-systems aspects present further challenges in their design. Understanding and taking advantage of the collective dynamics in such systems is crucial for implementing decentralized, self-organized solutions.
In this talk I will discuss fundamental issues and approaches for environments characterized by a high degree of uncertainty and unpredictability.

Short Bio: Dr. Botev is a senior researcher at the Computer Science and Communications (CSC) research unit of the Faculty of Science, Communication and Technology (FSTC) at the University of Luxembourg. His background is in Computer Science and Media Studies. Before joining the University in 2009, he was at the University of Trier (Germany) and City University, London (UK). His research interests include complex networks, self-organization, and collaborative socio-technical systems.
